The Metropolis of Gangra also Metropolis of Gaggra[note 1] was originally a bishopric see subjugated to the Metropolis of Ankyra, and later a metropolitan see of the Province of Paphlagonia, until the early 20th century. It was under the jurisdiction of the Patriarchate of Constantinople.

During the Byzantine period it was in charge of initially five, then four and finally three bishoprics. During the 7th century it ranked 15th among the metropolises of the Patriarchate of Constantinople. In the 13th century it was demoted to the 18th position. In the 14th century it briefly assumed the administration of the sees of Ankyra (twice), Sebasteia, Pompeiopolis and Gerane.
